Freezing vegetables

Vegetables are considered non-acidic food because they do not contain much acid in them. However, once they are picked from the farms or gardens, the deterioration process starts. This happens because vegetables are living organisms and continue their metabolic process even after they are harvested.

The enzymes present in vegetables start breaking down the cell walls, leading to changes in texture, flavour, and colour. Therefore, it is advised to consume freshly picked vegetables as soon as possible to get the maximum nutritional value from them. Additionally, storing vegetables properly in a cool, dry place can help slow down the deterioration process.

How to blanch vegetables for freezing

Blanching vegetables is a great way to preserve their fresh flavour and nutrients for later use. The best types of vegetables to blanch and freeze are those that are sturdy, like green beans, broccoli, cauliflower, carrots, and peas.

To start the blanching process, you will need a few essential pieces of equipment and materials. These include a large pot of boiling water, a bowl of ice water, a slotted spoon, and a timer.

To begin, prep your vegetables by washing them thoroughly and trimming any stems or leaves. Next, bring a large pot of water to a rolling boil on the stove. Once the water has reached the right temperature, add the vegetables to the pot, making sure they are completely submerged. Set the timer and allow the vegetables to boil for the recommended amount of time, which varies depending on the vegetable type and size.

When the timer goes off, use a slotted spoon to remove the vegetables from the boiling water and immediately transfer them to the bowl of ice water. This stops the cooking process and helps the vegetables retain their bright colour and crisp texture. After a few minutes in the ice water, remove the vegetables and drain any excess water.

Once your vegetables are blanched, pat them dry with a clean towel and store them in an airtight container or freezer bag. Label the container with the date and type of vegetable, and store it in the freezer for up to 8 months.

Blanching vegetables has many benefits, including preserving the nutritional content and flavour of the vegetables. When defrosting and cooking, it’s essential to remember that blanched vegetables cook faster than fresh ones, so they require less time on the heat.

Additionally, adding salt or herbs while blanching can enhance the flavour of the vegetables once they are defrosted. With these tips and tricks, you can enjoy fresh-tasting vegetables all year round.

Unblanched vegetables require the usual full cooking time, and although enzyme activity will not cause ff flavours to develop during their short stay in the freezer, you will lose one desirable side-effect of blanching. That is the reduction of the number of micro-organisms present so that spoilage is more likely if the defrosted vegetables are not cooked and used up immediately. Blanched vegetables pack down conveniently into less space and are almost fully cooked – two points in favour of blanching,

Cooking frozen vegetables

Cooking with frozen vegetables can be a game-changer in the kitchen, saving time and providing a quick solution for busy weeknights. The best way to cook frozen vegetables is to simply heat them through using your preferred cooking method. Boiling, steaming, and sautéing are all great options for cooking frozen vegetables straight from frozen, with boiling being the quickest and easiest method.

To boil

Add a little salt and very little water and cook covered for about half the usual cooking time.

To Saute

Use a frying pan with a lid, melt some butter, add partially thawed vegetables and toss over high heat for 1 minute. Cover and cook over lower heat until tender, seasoning to taste and stirring occasionally.

To complement the flavour of frozen vegetables, consider adding seasonings such as garlic, onion, herbs, or spices. A sprinkle of parmesan cheese or a drizzle of balsamic vinegar can also add a nice touch. As a general rule, avoid adding salt until the end of the cooking process to avoid drawing out excess water from the vegetables.

When it comes to presentation, aim to keep things simple to let the natural flavours of the vegetables shine through. Using colourful dishes and garnishes can add a pop of visual interest. Overall, cooking with frozen vegetables is a great way to save time and make healthy eating easy and accessible. With these tips and tricks, you can confidently use frozen vegetables in your cooking and enjoy flavorful and nutritious meals every day.
